When does a spring have more elastic potential energy? when does a spring have less elastic potential energy?

explanation:

specific heat is the amount of heat required to raise the temperature of a unit mass of a substance.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
